7.9.4. TAM INTERFACE CIRCUIT

This circuit is to switch between FAX receiving and the external TAM’s message recording 
automatically. This circuit consists of an EXT. TAM OFF-HOOK detect circuit, monitor 
transformer, multiplexer, amplifier, and VOX detect circuit.
For details, please refer to 

TAM INTERFACE SECTION

 ().

7.9.5. PULSE DIAL CIRCUIT AND ON / OFF HOOK CIRCUIT

While OFF-HOOK, RLY101 is ON. Q102 turns on by pin (138) of IC501 as well. On the other hand, 
while ON-HOOK, Q102 turns OFF by pin (138) of IC501, then the line turns OFF. ON/OFF-HOOK, 
controlled by pin (138) of IC501, makes the pulse dial operation possible.
IC501 (138) LINE RLY Low Level    CN517 (12)    CN101 (12)    Q102 OFF    RLY101 OFF : DC 
Loop OFF
IC501 (138) LINE RLY High Level    CN517 (12)    CN101 (12)    Q102 ON    RLY101 ON : DC 
Loop ON

7.9.6. LINE AMPLIFIER AND SIDE TONE CIRCUIT

1. Circuit Operation

The reception signal output from the line transformer T101 is 
input to pin (2) of IC101 via C112 and R112 and then the signal is 
amplified at pin (1) of IC101 and sent to the reception system at 
11.6dB.
The transmission signal goes through C571 and R579 and enters 
IC511-pin (2), where the signal is amplified to about 24.8dB. Then, 
it is output from pin (1) of IC101 and transmitted to T101 via C125 
and R121. If the side tone circuit is not applied, the transmission 
signal will return to the reception amplifier via C112 and R112. 
When the side tone circuit is active, the signal output from IC101 
pin (1) passes through C125, R123, C122, C115 and R115 and 
goes into the amplifier IC101 pin (3). This circuit is used to cancel 
the transmission return signal.
